MACHINE FOR STROPPING RAZORS.

SPECIFICATION forming part of Letters Patent No. 617,274, da n y 1899- Application filed February 5,1898. Serial No. 669,212. (No model.)

To all whont it may concern:

Be it known that I, GEORGE BESTON, a subject of the Queen of Great Britain and Ireland, and a resident of the city of Cork, Ireland, have invented a new and useful Improvement in Machines for Stropping Razors, of which the following is a specification.

The object of this invention is to perfect a machine having a flexible strop-band or strop of leather or other equivalent material capable of sharpening razors where all the operator has to do is to reciprocate the strop, the rest of the operation being automatically carried out by the mechanism.

My invention consists in certain novel combinations of parts, hereinafter set forth and claimed, whereby a bight-forrning roller and mechanism actuated thereby serve to reverse the razor-holder. Asingle flat spring,in combination with the actuating arm of said holder, serves to retire the edge of the razor from the strop at the end of each actuation. The guides of the strop are fixedly located within a substantial rigid frame, so as to keep the parts at all times in proper relation to each other, and the machine as a whole is rendered strong and simple in its construction.

In order that my invention may be the better understood, I will now proceed to describe the same in relation to the accompanying drawings hereto annexed, reference being had to the letters marked thereon.

Like letters refer to like parts in the various figures.

Figure 1 is a side elevation of the machine, the strop being ,broken away to show the mechanism. Fig. 2 is a plan of the same when stationary. Fig. 3 is a plan showing the position of the razor and holding mechanism when the strop is traveling in the direction of the arrows. Fig. 4 is a sectional plan; and Fig. 5 is a detail view of the holder, the jaws being shown separated.

To carry my invention into effect, I employ a frame A, provided with a clamping-screw B or other equivalent fastening device wherewith the machine can be affixed to a table or other support. Within this frame A, I arrange four pins or axles 0, upon which are loose sleeves or rollers D. These rollers serve as fixedly-located guides for a reciprocating flexible strop E, which passes around them and is led around a roller F. This is arranged as a bight-forming roller and is caused by the strop to rotate alternately on its fixed1ylocated axis in the frame A. The upper end of the roller E carries a disk G, upon which is a crank-pin II.

In the frame A and within the bight of the strop E is also pivoted a razor-holder J, which consists of two wings K, hinged to one another and spring-pressed by a bow-spring L, attached to the arms M, one of said arms being attached to one of the wings K and the other'arm to the other wing. This spring L puts a pressure on both of the wings K, so that they hold the razor between them. The spring L when its outer ends are pressed opens the holder J and releases the razor.

I may use a screw-tightening device in substitution of the spring L, if desirable.

At the upper part of the holder J, I arrange a rigid slotted arm N, which is adapted to en gage with the crank-pin II, so as to oscillate the arm N, and therewith the razor-holder, by

the alternate circular motion of said crank:

pin. The arm N also carries two lateral ex tensions O, which are adapted to coact with a flat steel spring P, carried on the frame A, so that immediately the strop E ceases to move the spring P, acting on one or other of the extensions 0, brings the holder J, with the .razor, away from the strop E into the midposition, and thus prevents the edge of the razor from cutting the strop on the return stroke. "When the return stroke is made, the motion of the strop reverses the position of the holder J and the other side of the razor is stropped, and the alternate action continues as long as the strop is pulled backward and forward.

The holder J is opened by pinching the arms N together by means of the projecting ends of the spring L and against the spring-pressure. A razor can then be removed or in serted into the holder, and the arms being released the inserted razor is held by spring= pressure.

Having thus described this invention, I declare that what I claim, and desire to secure by Letters Patent, is-

1. In a machine for stropping razors, the

combination with a reciprocating flexible strop, guided in the form of a bight, of a razor-holderpivoted within said bight, adapted to be rocked from side to side and provided with an actuating-arm carrying lateral extensions, and a flat spring which contacts with one or the other of said extensions for moving the razor-holder so as to retire the razor from contact with the strop at the end of each movement of the strop and before the return movement takes place, substantially as described.

2. An improved razor-stropping machine composed of a rigid frame, means for attaching said frame to a suitable support, fixedlylocated guide-rollers within said frame, a reciprocating flexible strop guided by said rollers, a bight-forming roller rotated alternately by said strop and provided at one end with a GEORGE BESTON.
